DISK GR-AlN-DRILL.

SPECIFICATION forming part f Letters Patent 110.716,774, dated December 23, 1902. Application filed July 5, 1902. `Serial No. 114,505. (No model.)

To a/ZZ whom, t may concern,.-

Be it known that we, J OHN W. SMITH and J AMES M OOUGHLIN, of Liberty, in the county. of Union and State of Indiana, have invented' anew and useful Improvement in Disk Grain- Drills, of which the following is a specification.

Our invention relates to improvements in disk grain-drills, and has for its object to pro- Io vide a grain-drill which shall be simple, compact, and eficient. Heretofore in devices of this character the seed-conduit has been usually located on the convex side of a concavoconvex disk and made in one piece. In our device the seed-conduit is made in two sections, the upper one being located on the concave side of the disk and the lower section on the convex side thereof, the two sections communicating through a hollow hub carry'- zo ing the disk.

Our invention further consists in certain novel constructions and combinations of parts, as will be hereinafter fully described, and pointed out in the claims. A

Figure l' is a vertical section through the disk and seed-conduits. Fig. 2 is an elevation of the inside of the disk and attached drag. Fig. 8 is a similar view of the outside of the disk, showing lower seed-conduit and drag- 3o bar. Fig. 4 is a view of the inside face of the lower seed-conduit.

In carrying out our invention we use, preferably, a concavo-convex disk A, havinga central circular opening into which is bolted an annular iianged ring a, forming a boxing. Said boxing iits on the hub B, which is provided with a downwardly-extending lug b, provided with a curved groove b. The upper side of the hub is also provided with a 4o curved groove, with the saine radius as the groove in the lug b. Within the grooves the inner edge of the ring d lits and is adapted to revolve. Extending upwardly from the hub and preferably integral therewith is the curved upper seed-conduit O, which extends upwardly at least to the periphery of the disk A and preferably beyond it. The seed-conduit O extends into or preferably through the hub in a curved line and has its discharge 5o end at the convex side of the disk.

Secured onthe convex side of the disk A is the lower 'seed-conduit D, which is provided on its inner face with the inwardly-extending flange d, which is arc-shaped and adapted to iit over and bear upon the periphery of the 5 5 annular liange of the ring boxing 0L. Said lower seed-conduit is secured adjustably to the hub B by means of a screw-bolt d', passing through a curved horizontal slot d2 therein and. screwing into the hub. The lower 6o seed-conduit D is provided with a forwardlyextending lug or arm D', .provided with a curved diagonal slot D2, by 'means of which and a bolt d3 it is secured to drag-bar E. Projecting from the inner face of the lower seed-conduit D are the lugs'D3 D3, between which is journaled an antifriction-roller D4, adapted to bear against the edge of the boxing a of the disk A.

The hub B on the concave side of the disk 7o is provided with the horizontal extension B', which projects to the front and rear of its center, said extension being Vchanneled to receive the drag-bar E', which is secured in the channel by bolts c.

The lower seed-conduit is also provided on its inner face with the curved ribs o r anges D5, which extend from about the center of the upper circular portion to the lo Werend of the said conduit, the edges of said flanges con- 8o forming in curvature to the convex face of the disk A. Theinner upper edges of the conduitD are curved inwardly and also lit the convex face of the disk A. The outer face of the conduit D has secured to it near its upper4 portion the drag-bar E by the bolts before mentioned. The lower seed-conduit D has a rearward inclination, and its lower end is never toextend beyond the periphery of the disk. p

By adjustably connecting the lower seedconduit with the hub and drag-bar by the curved slots the said conduit may be moved in the arc of a circle, thereby permitting the seed to be placed in the ground at a greater 95 or less depth with the saine amount of pressure and also permits the placing of the seed in a wide or narrow seed-bed, as desired, without moving or changing the position of the upper seed-conduit. By making the seedloo conduits in two sections, as shown,we are able to place the upper seed-conduit on the concave side of the disk, and thus prevent dirt and trash accumulating between the upper seed-conduit and the concave side of the disk.

By placing the upper seed-conduit on the concave side of the disk and by curving the lowerend of said conduit, as shown, the seed in rolling over the curve in the lower end of the upper seed-conduit will be more evenly distributed than would be the case if the upper seed-conduit were in a perpendicular position.

While this device is shown applied to a concavo-convex disk, it will also work efficiently on a dat disk, and as it consists of few parts it is manifest that it can be manufactured very cheaply.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

I. In a seeding device, a disk a hub secured thereto having a passage therethrough, upperandlowerconduitscommunicatingwith said passage whereby seed may be conveyed from the upper seed-conduit to the lower seedconduit.

2.
